Legacy Parkway is an 11.5-mile-long (18.5 km) four-lane controlled-access parkway located almost completely within Davis County in the northern part of the U.S. state of Utah. The parkway travels north from Interstate 215 (I-215) in northwestern Salt Lake City to an interchange named the Wasatch Weave in Farmington with two intermediate interchanges providing access to Woods Cross and Centerville. Wetlands of the nearby Great Salt Lake and nature preserves border the western side of the parkway while the eastern side roughly parallels Union Pacific and Utah Transit Authority rail lines and I-15. On average, between 20,000 and 23,000 vehicles use the parkway daily.
